Non-monotone Submodular Maximization with Nearly Optimal Adaptivity and Query Complexity

open access: yes, 2019
Submodular maximization is a general optimization problem with a wide range of applications in machine learning (e.g., active learning, clustering, and feature selection). In large-scale optimization, the parallel running time of an algorithm is governed

Connectivity of submodular functions

open access: yesDiscrete Mathematics, 1992
This paper relates the connectivity of submodular functions \(f\) to that of certain submodular functions which are derived from \(f\). Here the function \(f\) on \(S\) is submodular if \(f(A)+f(B)\geq f(A\cup B)+f(A\cap B)\) for all subsets \(A\) and \(B\) of \(S\).

Low-Delay and High-Coverage Water Distribution Networks Monitoring Using Mobile Sensors

open access: yesIEEE Access, 2019
Urban water distribution networks (WDNs) are usually threatened by leakage, reflux, infiltration and internal pollution. To ensure the safety of water supply, it is essential to properly monitor the WDNs.
